Is how little people understand the importance of turn and burn or how to take advantage of power plays (Numbers advantage)

So I've decided to join the NIN brigade (let's be honest the job is too good not to play) and the amount of times I've isolated a target for nobody to help them, killed them, gone in behind and got a death link chain is obscene.

This can be stopped by a simple turn and burn exercise forcing me to play more safe instead of target hunting or you can force some important cooldowns out of me forcing me to leave the fight to elixir at a safe distance and change my approach.

There's also a huge lack of peeling

What is Peeling? When a person attacks/ccs an opponent that is attacking a team mate forcing the disengage or it'll turn into a 2 v 1 which inevitably leads to the attackers death.

Why it peeling important?

It can easily net you a 4 v 5 advantage because if someone is going full on kill greedy, you can punish it hard and should punish it hard.

Also knowing when to push advantage is important too.

I can draw a lot of attention onto myself, getting chased across the map and guess what? I want them to chase me, if they won't disengage and will chase me thirsting for a kill, I can keep them busy, as a NIN I've got the kit to keep them following me for a long time, I've had games where I've had 3 people chase me all the way across the map, only for somehow my 4 team mates to scratch their backsides doing nothing as the 2 enemy players that didn't start chasing push the crystal along.

You're Four Versus Two, the Other Three are chasing me and thus not at the Objective, take advantage, you got several seconds to a minute to do something if someone goes that kill thirsty before I have to get out of dodge and run back to the team, USE IT

These are all basic things folks, use them.
